This report documents the process used in Canada to harmonize heavy truck size and weight regulations across the country and provides insights on how lessons learned from the Canadian experience might be applied in a U.S. context. It will provide a valuable contribution to the ongoing discussion of truck size and weight regulation in the United States. The authors include a summary of the regulatory framework for truck size and weight regulation in the United States and the efforts that have been made over time to achieve greater uniformity. This report will be of interest to truck size and weight regulators in the United States, who face similar jurisdictional challenges to develop and implement regulations that permit common configurations of heavy trucks that can operate legally across the country without compromising safety concerns or creating excessive impacts on road pavement.
